My plasterer has ruined my new quarry floor tiles and the grout with SBR and waterproof render.
Before plastering and rendering he covered the quarry floor in old 'protective' sheeting.
However the SBR and waterproof render he used has soaked through the sheeting and dried underneath and onto my quarry floor tiles and all the grout joints in between.
I've tried scrubbing but I cannot get it off.
I told the plasterer and he flippantly told me to use flash.
Can anyone advise on what I should do!!
